what type of model, and its precision/quant. DirectML is stale and likely running into issues these days running some models. especially with comfy-kitchen being involved. From what I can see there is no official support for DirectML for C-K.
Support for your gpu is pretty limited. SM's ComfyUI-Zluda is HIP SDK 6.4 only (and may hit the same issue), SDNext may be a better shot.
If you use SDNext you'll have to extract special rocBLAS libraries into C:/Program Files/AMD/rocm/6.2 from here:
https://github.com/YellowRoseCx/koboldcpp-rocm/releases/tag/deps-v6.2.0 (pick one, not sure which one is the best to choose)
What happened?
Hello, dear Stability Matrix users, please tell me, I have all the components from AMD, I can only run the Comfortable UI on the CPU, the rest (DirectML, ROCm) gives an error, what should I do about it? The screenshot shows the error.
